The reason I would like to know is that I have a 36v 350W controller driving a hall effect front wheel with 2 x 8000ah 18v Lipos in series. If I add another 18volt lipo this will give me 54 volts - surely too much? So if I acquire a 48volt controller and another 18v lipo and then over volt to...

Is it better to have multiple battery's or keep the number to a minimum. The reason I ask is I'm looking at building my battery pack for my bike and after seeing the multiple configuration options that can be made ( price very similar ) For example 2 x 18.5V 8000maH - wired in series or 4 x...

BMS battery's seem pretty good but the postage is high and the possible dreaded import tax and nice post office fee puts me off a bit. The idea of building my own pack is appealing but how would you charge up 2 or even 4 lipos at the same time? Would you need to charge each pack on its on which...

The voltage between the red and black throttle wires on the controller. 4.61V Plug in the throttle and measure them again while plugged. 3.61V With the throttle still plugged in, measure between the black and third wire. 0.88V Hold the throttle fully open and measure the voltage between...
